Summary:
A handfish with long thin yellowish to orange streaks and stripes on the head and body, large dark spots on the tail, and black or orange spots on the dorsal, anal, pectoral and pelvic fins.

More Info


Distribution

Endemic to eastern and southern Australia, from off North Stradbroke Island, Queensland, to south of  Middini Beach in the Great Australian Bight, Western Australia, and off northern and eastern Tasmania south to the D’Entrecasteaux Channel.

Bottom dwelling on soft substrates in depths of 18-210 metres, although one individual was trawled bewteen 123 to 277 m (the actual capture depth is unknown).

Features

Meristic features: Dorsal fin I + II + 17-18; Anal fin 9-10; Caudal fin 9; Pectoral fin 7: Pelvic fin I, 4.
Body short, tapering, posterior half noticeably slender, belly rarely enlarged. Head large, depth greater than depth of expanded tail, subtriangular in cross-section; eyes small; mouth small, reaching to below front edge of eye; teeth tiny, narrow band in each jaw; gill opening a tiny tubular pore behind pectoral-fin base.

Scales absent, skin covered in spinules; fleshy filaments present on body and upper base of pectoral fin but absent between gill pore and origin of soft dorsal fin.

Dorsal fin in three unconnected parts, illicium (first spine), spinous dorsal and soft dorsal; illicium prominent, based on tip of snout, undamaged lure less than 20% of whole structure; spinous dorsal on top of head, tall, anterior margin of first spine serrated; soft dorsal tall, longest ray less than 80% longest dorsal fin spine, lower half of fin generally not covered with skin; anal fin below posterior half of soft dorsal; caudal fin narrow, rounded. Pectoral fin arm-like, tip directed laterally forwards and downwards. Pelvic fins jugular.

Colour

Pale with narrow yellowish or orange longitudinal lines, occasionally with a few spots; dorsal, caudal and pectoral fins colourless with black or orange spots; pelvic and anal fins mostly colourless or white. 

Biology

Egg diameter 1.7-1.9 mm.

Fisheries

Taken as bycatch on scallop dredges, and occasionally by trawlers and Danish seiners.

Similar Species

Differs from the Spotted handfish, Brachionichthys hirsutus, in having a larger eye, a longer 'fishing rod' with a smaller lure at the tip, a longer first dorsal-fin ray, fewer rays in the second dorsal fin and hence a shorter fin base. B. australis is patterned with long thin streaks and stripes (vs small spots or short streaks) and the tail is covered in large dark spots (vs the tail densely covered in fine spots with a dark submarginal band in B. hirsutus).

Etymology

The specific name is from the latin australis meaning 'southern', in reference to its wide distribution in southern Australia.
